If you are examining how data is stored and managed in an enterprise, which domain/layer is the focus?

• A. Data Layer
• B. Application/Information System Layer
• C. Environment Layer
• D. Technology Layer

Answer: (A)

Data storage and governance are handled by the data layer. This layer defines how data is stored (databases, data warehouses, data lakes), how it’s modeled (schemas and data types), and how it’s governed (quality, metadata, access controls) to keep information consistent and accessible across the enterprise. The Application/Information System Layer is where software uses and processes that data to deliver business functionality, while the Environment Layer covers the runtime context, security, and operational policies, and the Technology Layer includes the underlying hardware, networks, and platform software. Since the question focuses on how data is stored and managed, the data layer is the best fit.
